Eaton L2120CW Watertight locking connector - IP67
Part Number: L2120CW
Quick Summary
Eaton L2120CW watertight locking connector securely connects industrial power circuits. Moisture ingress and wiring reliability are common pain points in harsh environments, and this design targets both with a rugged, back-wired approach. It carries RoHS compliance, NOM cULus listing, and IP67 protection to keep contacts sealed in wet or dusty settings. By combining a yellow nylon housing, nickel-plated brass contacts, and a Santoprene elastomeric seal, it delivers dependable performance in enclosures, control panels, and outdoor machinery. For engineers and procurement teams, the result is fewer field callbacks, faster installations, and improved regulatory compliance across sites.

FAQs
The L2120CW uses a four-pole L21-20 configuration designed for 3ØY 120/208 V systems with five conductors (including grounding). It supports back-wiring with #18-10 AWG conductors and provides a secure, watertight connection suited for industrial panels, motors, and receptacle boxes. This combination simplifies motor control and power distribution in harsh environments.
It features IP67 protection, a Santoprene elastomeric seal, and a Nylon housing with a watertight locking design. These elements protect against moisture, dust, and temperature cycling, reducing corrosion risk and downtime for outdoor equipment, conveyors, and outdoor control stations.
Back wiring requires securing each #18-10 AWG conductor into the appropriate terminal with a torque of 14-16 in-lbf. Ensure the 4-pole, 5-wire configuration is correctly connected for a complete L21-20 circuit. Follow the supplier datasheet for crimp ferrule usage and enclosure wire routing to maintain integrity.
The L2120CW is RoHS compliant and NOM/cULus listed, with IP67 environmental protection. These certifications support regulatory compliance for many North American and global deployments, while the IP67 rating confirms suitability for wet and dusty environments in industrial facilities.
By leveraging waterproof sealing, rugged construction, and back-wire efficiency, the L2120CW reduces field rework, speeds installations, and improves system reliability. Its NAS-style protection and 20 A rating support durable power distribution in motor control centers, conveyors, and outdoor equipment, delivering measurable uptime and maintenance savings.
